Cast WindowExtIOS from Window in Bevy

Question

I'm using beau which internally use winit.

I'm running my app in iOS devices so the way I have configured my project winit it should create a Window of type WindowExtIOS

fn setup_raw_window(mut windows: NonSend<WinitWindows>, window_query: Query<Entity, With<PrimaryWindow>>) {
    let entity = window_query.single();
    let raw_window:&window::Window= windows.get_window(entity).unwrap();
    // How to cast to WindowExtIOS
}

The problem is that I don't see how to make the cast to WindowExtIOS since even watching with the IDE that the class exist and is in my package, rust and bevy cannot accept the package winit::platform::iOS

Any idea what to do?

Regards.
